Abstract:
A field experiment was conducted at the Agronomy field of Sher-e-Bangla
Agricultural University, Dhaka during the period from October- 2019 to February
2020 in Rabi season to investigate the effects of boron on growth, yield and yield
attributes of mustard. The experiment consisted of two factors, and following splitplot
design with three replications. Factor A: mustard varieties (2) viz. V

. Data on different parameters were collected for assessing results for this
experiment and showed significant variation on growth, yield and yield contributing
characteristics of mustard due to the effect of different treatments and their
combinations. In case of varieties, BARI Sarisha-14 (V
1
) recorded the maximum
number of silique plant
-1
(101.87), siliqua length (9.55 cm), seeds siliqua
(22.51),
1000-seed weight (3.59 g), seed yield (1.63 t ha
-1
), stover yield (3.73 t ha
), biological
yield (5.36 t ha
-1
) and harvest index (30.36 %). Due to boron levels, 2.0 kg boron ha
(B

) treated plots recorded the maximum number of silique plant
-1
(100.50), siliqua
length (9.54 cm), seeds siliqua
-1
(23.67), 1000 seeds weight (3.67 g), seed yield (1.76 t
ha
-1
), stover yield (3.90 t ha
-1
), biological yield (5.67 t ha
-1
) and harvest index (31.08
%). On the other hand BARI Sarisha-14 (V
1
) along with 2.0 kg boron ha
) treated
plots recorded the maximum number of silique plant
-1
(115.00), siliqua length (10.84
cm), seeds siliqua
-1
(26.34), 1000-seed weight (3.82 g), seed yield (1.87 t ha
), stover
yield (3.73 t ha
-1
), biological yield (5.85 t ha
-1
) and harvest index (31.89 %). However
mustard varieties showed linear relationship between different boron levels on seed
yield of mustard and correlation ship between seed yield and yield contributing
characteristics.
